Hello, 

I'm searching how to prevent a RadTileViewItem to automatically resize when switching to a different RadTabItem.

In our WPF application, we use the RadTabControl. The RadTabItems are dinamically created from user input. In a particular RadTabItem, I've include a RadTileView that is populated dinamically from ItemsSource.

The ContentChangeMode is set to Manual and I have a method managing it. It works well.

My problem is that when I maximize one item, its content switch to an editable control. The RadTileView is in a TabItem, so the user could click on an other Tab. When this occurs, all RadTileViewItems are refresh and them states are set to Restored. The RadTileViewItem I previously set to maximized is now Restored but his content is always linke to the "editable control".

My wish is to prevent this. The first solution possible is to block the MaximizedItem to set Restore state. Or second, when switching to Restore, force to set his state to NormalContent. These 2 solutions are OK for me.

Could someone help me or has an example of this?

Sorry if the question had already been posted, I didn't found someting.

And sorry for my poor english ;-)

Best regards

Hello,

I am developing an app for a Windows 10 Tablet that requires a picture to be taken.

I have set up a RadWebCam control, but when I open the settings menu on the tablet it takes 2-3 minutes of "Not Responding" before it loads the settings menu. Additionally it is very slow when adjusting the settings. The only reason I need the settings is for the Zoom control. Is it possible for me to change the zoom programmatically? I would like to add a +/- zoom button, but I cannot find anything on how to do this.

My second issue is that the app needs to run in portrait mode, but the camera is in horizontal mode. Is there any way I can change the rotation of the web cam? If I rotate the control it will rotate the bottom panel as well.

Hi Support team,

even if animation is disabled, the expander is still showing some sort of animation when Windows 11 theme is applied.

This can be reproduced with Telerik samples.

Is there a way to remove that animation entirely so that the content gets displayed immidiateley ?

Hey,

I'm looking to have a RadSyntaxEditor's horizontal scroll bar react to a trackpad or mouse wheel input.

Vertical scrolling works just fine, so I can hide the verticalscrollbar but I need to select the horizontal one to move horizontally.

Is there a way to set it for horizontal as well? Did I miss a setting somewhere?

I tried this solution : Horizontal Scrolling w/ Mouse Wheel/Trackpad in UI for WPF | Telerik Forums but it didn't work for me.

I don't know if it's because this solution is in a window and I'm in an usercontrol.

Thanks in advance !

Hi,

I wanted to use "search as you type" functionality (http://docs.telerik.com/devtools/wpf/controls/radgridview/features/search-as-you-type.html) in a TreeListView, but looks like it doesn't work for it even though it's inherited from GridView.

I tried it on a new blank project and confirmed my suspicion:

doesn't show a search panel, but 

works without any issues.

Is this intended behaviour, or can we hope for a fix?

Thank you.

Hello,

I followed your solution on this link to apply a string format on the Header of the column in the RadGridView:

https://www.telerik.com/forums/stringformat-not-working-for-gridviewdatacolumn-header

With this solution, if the bound property has a value "test", in the TextBlock.Text inside the header I will show "test 123" ("123" came from the StringFormat).

This solution works but I face a bug when I use it with another functionality. I have implemented a button that on click opens a ListBox on a ContextMenu to show/hide the RadGridViewColumns). See the following link:

https://www.telerik.com/forums/add-button-to-radgridview-column-header

The RadGridView.Columns are bound to the ListBox.

The ListBoxItem.Template has a Checkbox where the IsChecked property is bound to the Column visibility state and the Content property is bound to the Column header. 

If the Listbox is shown (by click on a button, the ListBox is displayed on a ContextMenu), the Header template is dissapeared from the GridViewDataColumn.Header and it is shown on the ListBoxItem. It likes the template is "moved".

If I put the DataTemplate on a resource with x:Shared=False then it still dissapears from the header and it appears twice on the ListBoxItem.

Note:

1. I tried to use the Header without a DataTemplate but I can't use a converter to append the "123" because I already have one converter that can't have other functionality.

2. My current workaround is to do the converter code and the text append on the code behind of the xaml. Then I can bind the xaml.cs String property to the GridViewDataColumn.Header and remove the DataTemplate. The problem with this solution is that I need to do this on each xaml, and cannot be set on a style. In addition, I don't want to use code behind at all.

3. Any workaround without using the DataTemplate will work for me. I can "live" with that problem if you help me solving this specific case because I usually don't use DataTemplates on headers at all.

4. If you can look at your code, I would appreciate if you can think how the DataTemplate is dissapeared. I think that you have a bug somewhere because a Binding should not remove a Template from your control.

The bug is the same as described in this post (screenshot attached)

https://www.telerik.com/forums/gridview-columns-headers-disappearing-after-binding-to-controlpanel

I need a workaround to display the complete text without DataTemplate, because the solution here of adding DataTemplate for all columns of the application is not aceptable. Maybe there is a way to trigger the Context on the ListBoxItem and changed the binding according to the content type?

Thank you,

Alex.

Hello,

I have RadRibbonTab that I am binding an item source to. This item source contains a GroupName as well as a list of other items that can be used to create RadRibbonButtons. My problem is that I am seeing an extra separator after each RadRibbonGroup and I'm not sure why. If I try to create my own template for the RadRibbonGroup this extra separator goes away but I'd prefer to not have to do this. I've attached an image of what I'm seeing. What suggestions are there to get rid of this separator?

Here is the xaml in question:

<telerik:RadRibbonTab Header="Dynamic Display" x:Name="DisplayMenu" ItemsSource="{Binding RelativeSource={RelativeSource AncestorType={x:Type local:RibbonViewContainer}}, Path=DisplayList}">
    <ItemsControl.ItemTemplate>
        <DataTemplate>
            <telerik:RadRibbonGroup Header="Test Header" ItemsSource="{Binding List}" >

                <ItemsControl.ItemTemplate>
                    <DataTemplate>
                        <telerik:RadRibbonButton Size="{Binding Size}"
                                                         Text="Test Text"
                                                         Command="{Binding}"
                                                         CommandParameter="{Binding Text}"
                                                         LargeImage="{Binding Image}"
                                                         ToolTip="{Binding Tooltip}"
                                                         ClickMode="Press"/>
                    </DataTemplate>
                </ItemsControl.ItemTemplate>


            </telerik:RadRibbonGroup>
        </DataTemplate>
    </ItemsControl.ItemTemplate>
</telerik:RadRibbonTab>

Hi everybody.

Does Anyone have any idea why the Radgridview is much faster when run the app through Visual Studio? it's much slower when run the app locally specially when scrolling with large amount of data.

Thanks
